Print the failed instruction stream as a contiguous stream of hex. This
is closer to something you could throw at a disassembler than 0xHH 0xHH
0xHH.
Also, use the debug.h 'raw' stdio-aware printf helper to avoid the
cascading
line
effect.
Add an implementatation of the 'Virtual Machine Generation ID' spec to
Bhyve. The spec provides a randomly generated GUID (at bhyve start) in
device memory, along with an ACPI device with _CID VM_Gen_Counter and ADDR
evaluating to a Package pointing at that GUID.
A GPE is defined which Notifies the ACPI Device when the generation changes
(such as when a snapshot is rolled back). At this time, Bhyve does not
support snapshotting, so the GPE is never actually raised.

To allow more general use of the bootrom region, separate initialization from
allocation, and allocation from loading a file.
The bootrom segment is the high 16MB of the low 4GB region.
Each allocation in the segment creates a new mapping with specified protection.
By default, allocation begins at the low end of the range. However, the
BOOTROM_ALLOC_TOP flag is provided to locate a provided bootrom in the high
region it is expected to be in.
The existing ROM-file loading code is refactored to use the new interface.

GPIO drivers who supports interrupts report them in the caps
(obtain via the getcaps method) but gpioctl doesn't know
how to interpret this and print "UNKNOWN" for each one of them.
Even if we don't have userland gpio interrupts support for now

Recently added/changed lines in various kernel configs have caused some
buffer overflows that went undetected. These were detected with a config
built using -fno-common as these line buffers smashed one of our arrays,
then further triaged with ASAN.
Double the sizes; this is really not a great fix, but addresses the
immediate need until someone rewrites config. While here, add some bounds
checking so that we don't need to detect this by random bus errors or other
weird failures.

This is mostly two problems spread out far and wide:
- ypldap_process should be declared properly
- debug is defined differently in many programs
For the latter, just extern it and define it everywhere that actually needs
it. This mostly works out nicely for ^/libexec/ypxfr, which can remove the
assignment at the beginning of main in favor of defining it properly.
-fno-common will become the default in GCC10/LLVM11.

Notably, the default IFS contains space/tab, thus any leading/trailing

Set IFS= for just the read lines to mitigate this, allowing the user to be

As a followup to the use of login.conf environment vars (other than PATH) in
cron, this patch adds PATH (and HOME) to the list of login.conf settings
respected.
The new logic is as follows:
1. SHELL is always _PATH_BSHELL unless explicitly overridden in the crontab
file itself; no other settings are respected. This is unchanged.
2. PATH is taken from the first of: crontab file, login.conf, _PATH_DEFPATH
3. HOME is taken from the first of: crontab file, login.conf, passwd entry,
unset
4. The current directory for invoking the command is taken from the crontab
file's value of HOME (existing behavior), or the passwd entry, but not
anywhere else (so it might not equal HOME if that was set in login.conf).

Unexplained in my previous commit to gas, -fno-common will become the

The SQHD field of a Completion Queue entry indicates the current
Submission Queue head pointer value. The head pointer represents the
next entry to be consumed and is updated after consuming the current
entry.
In the Admin queue processing, the current code updates the head pointer
after reporting the value to the host via the SQHD. This gives the
impression that the Controller is perpetually one command behind in its
processing of the Admin SQ. And while this doesn't appear to bother some
initiators, it is wrong.
Fix is to update the SQ head pointer prior to writing the SQHD value in
the completion.
While here, fix missed update of dword 0 (cdw0) in the completion
message.

The bhyve NVMe emulation has a race in the logic which generates command
completion interrupts. On FreeBSD guests, this manifests as kernel log
messages similar to:
nvme0: Missing interrupt
The NVMe emulation code sets a per-submission queue "busy" flag while
processing the submission queue, and only generates an interrupt when
the submission queue is not busy.
Aside from being counter to the NVMe design (i.e. interrupt properties
are tied to the completion queue) and adding complexity (e.g. exceptions
to not generating an interrupt when "busy"), it causes a race condition
under the following conditions:
- guest OS has no outstanding interrupts
- guest OS submits a single NVMe IO command
- bhyve emulation processes the SQ and sets the "busy" flag
- bhyve emulation submits the asynchronous IO to the backing storage
- IO request to the backing storage completes before the SQ processing
loop exits and doesn't generate an interrupt because the SQ is "busy"
- bhyve emulation finishes processing the SQ and clears the "busy" flag
Fix is to remove the "busy" flag and generate an interrupt when the CQ
head and tail pointers do not match.

This adds support for the Dataset Management (DSM) command to the NVMe
emulation in general, and more specifically, for the deallocate
attribute (a.k.a. trim in the ATA protocol). If the backing storage for
the namespace supports delete (i.e. deallocate), setting the deallocate
attribute in a DSM will trim/delete the requested LBA ranges in the
underlying storage.

Property-based filters allow substring and regular expressions
(see re_format(7)) matching against various message attributes.
Filter specification starts with '#:' or ':' followed by three
comma-separated fields property, operator, "value". Value must be
double-quoted. A double quote and backslash must be escaped by a
blackslash.
Following properties are supported as test value:
o msg - body of the message received;
o programname - program name sent the message;
o hostname - hostname of message's originator;
o source - an alias for hostname.
Supported operators:
o contains - true if filter value is found as a substring of property;
o isequal - true if filter value is equal to property;
o startswith - true if property starts with filter value;
o regex - true if property matches basic regular expression defined
in filter value;
o ereregex - true if property matches extended regular expression
defined in filter value;
Operator may be prefixed by '!' to invert compare logic or by
'icase_' to make comparison function case insensitive.
